Mischkolz, J. M., Schellenberg, M. P. and Lamb, E. G. 2013. Early productivity and crude protein content of establishing forage swards composed of combinations of native grass and legume species in mixed-grassland ecoregions. Can. J. Plant Sci. 93: 445–454. We evaluated the early establishment productivity of forage swards of native, perennial, cool and warm season grasses, and legumes as they have the potential to provide non-invasive, productive, and drought resistant rangelands. Seven species with agronomic potential and a broad native geographic distribution were selected for testing including: nodding brome [Bromus anomalus (Coult.)], blue bunch wheatgrass [Pseudoregneria spicata (Pursh)], western wheatgrass [Pascopyrum smithii (Rydb.)], side oats grama [Bouteloua curtipendula (Michx.)], little blue stem [Schizachyrium scoparium (Michx.)], purple prairie clover [Dalea purpurea (Vent.)], and white prairie clover [Dalea candida (Willd.)]. Forage swards, including all seven monocultures, 21 two-species mixtures and a mixture with all species, were planted in two sites, Saskatoon and Swift Current, Saskatchewan. Western wheatgrass (WWG) had the highest overall plant density and the strongest effect on the forage yield of the forage swards; however, productivity and crude protein content were not reduced when other species were also included in the forage sward. Dalea spp. did not establish as well as the other species, but had the highest crude protein concentrations. This work provides insight into forage sward development at the establishment stage; additional work is required to determine long-term species impacts for well established forage swards.

Yield And Quality

Maize is the very important silage source in the world. Timely harvesting ensure high maize forage yield and quality. Therefore, the study focused on the effects of four harvesting times (starting at the 12 August every 7 days) on yield and qualitative parameters of forage green mass of maize hybrid ZP 677. The experiment was set in Vojvodina Province, Serbia, during the 2013 and 2014 growing seasons. Plant height, stem diameter, number of leaves per plant, ear percentage, forage yield, dry matter content and crude protein content were higher, while stem percentage was lower in 2014 with favorable climatic condition. Forage yield, crude protein content, ADF and NDF decreased, while dry matter content significantly increased with delay in harvesting. The maize hybrid should be harvested when the milk line is three-quarter of the way down the grain that is in the third decade of August.

Field trials were conducted at the Agriculture Canada Research Station, Agassiz, B.C. from 1986 to 1988 to study, under south coastal British Columbia conditions, the use of companion crops in grass establishment. Orchardgrass (Dactylis glomerata L.), perennial ryegrass (Lolium perenne L.), or a mixture of the two was seeded with either oats (Avena sativa L.) or barley (Hordeum vulgare L.) as a companion crop, or as sole crops with weeds either allowed to grow or controlled by herbicide. First cut yields were highest and second cut yields lowest in the establishment year whenever a companion crop was used. Companion crops had no effect on third cut yield in the establishment year, nor on yield the following year. Total yield in the establishment year was highest whenever a companion crop was used due to the higher forage yield of annual cereals than perennial grass at first cut. Proportion of weeds in the first cut was lowest with a companion crop and highest where grass was seeded alone without herbicide. Crude protein content of the first cut was lowest with a companion crop while establishment method had no effect on crude protein content of subsequent cuts. In the second year crude protein content of the forage was highest with ryegrass and lowest with orchardgrass particularly if sprayed with herbicide. A companion cereal crop can be used when seeding forage grasses in south coastal British Columbia, and there is no advantage to using a herbicide for weed control on forage seedlings grown without a companion crop.Key words: Companion crop, establishment, forages, British Columbia

SUMMARYIf corn-soyabean intercrops are to replace corn grown alone, maintenance of yield and improvements in forage quality are important. Total yields and inter-crop competition in corn-soyabean intercropping experiments have been discussed previously (Putnam et al., 1985). In Part II yield composition, components and protein content are presented for intercrops of varying planting patterns and corn densities. Most intercrop patterns produced more forage than sole crops compared at the same yield ratio of corn-soyabean as in the intercrop harvested mixture. At high plant density ear yields in the intercrop were increased while in sole crops they were reduced or unaffected. The increase was a result of an increased number of ears, weight per ear and kernel, and number of kernels per row in the intercrops. Increases in crude protein content over sole crop corn of 11–51% were shown for the various intercrop treatments. Crude protein yields in the intercrops were greater than either sole crop in 1981 and greater than corn and similar to soyabean in 1982, and greater than the crude protein yields expected from an equal planted area of sole crop corn and soyabean in both years. Intercrop forage quality was improved over sole corn both by the addition of protein from soyabean pods and an increased ear: stover ratio of the intercropped corn.

An experiment was performed at the AES-UPR Gurabo Substation to evaluate atrazine, simazine, diuron, and tebuthiuron for preemergence control of weeds in a stargrass pasture. Tebuthiuron at 3.36 kg a.i./ha was the most effective, and tebuthiuron at 1.68 kg a.i./ha was the second most effective. The remaining herbicides also provided satisfactory weed control. At 3.36 kg a.i./ha, tebuthiuron was somewhat phytotoxic to stargrass, but less so at 1.68 kg a.i./ha. None of the other herbicides produced severe stargrass injury. Stargrass yield was not affected by any of the herbicides. Crude protein content of stargrass was not affected by any herbicide tested.

Forage Yields

Forage yields of Dominant winter rye clipped in the spring in a series of 12 treatments ranged from about [Formula: see text] ton to over 2 tons of D.M./acre. Clipping reduced grain yields by at least 10% and several clipping treatments prevented any grain production. The lowest forage yield and the least reduction in grain yield resulted from a single early clipping. Forage yield increased by [Formula: see text] ton D.M./acre for each week’s delay in clipping with correspondingly greater reduction in grain yield. Crude protein content of the forage decreased from 25 to 13% in a 3-week period. Increased forage yields were obtained when the interval between repeated clipping was increased from 1 to 2, 3, or 4 weeks. Protein levels were maintained at over 25% for 3 months with weekly clipping. Height, maturity, and ergot incidence were adversely affected by all clipping treatments.
